Hi, I suppose there is a minor error in the example of the filter() function in 5.1.3 part of the document.

------------------------------------------------------------------
filter(function, sequence) returns a sequence consisting of those items from the sequence for which function(item) is true. If sequence is a string or tuple, the result will be of the same type; otherwise, it is always a list. For example, to compute a sequence of numbers not divisible by 2 or 3:

>>>
>>> def f(x): return x % 2 != 0 and x % 3 != 0
...
>>> filter(f, range(2, 25))
[5, 7, 11, 13, 17, 19, 23]
------------------------------------------------------------------

I think what the example does is "to compute a sequence of numbers not divisible by 2 and 3", not "2 or 3".

For me the text is correct.  However, it depends on parsing the English sentence in the right way, which can be confusing.  The prose means "not (divisible by 2 or 3)" which is equivalent to "not divisible by 2 and not divisible by 3", therefore the Python code has an "and" operator.

It would probably be best to remove the negation, which also removes the ambiguity: "compute a sequence of numbers divisible by 2 or 3" or such.

Ah yes. You are right, Georg.
And as you suggested, it might be better to remove this ambiguity, for people with poor parsing skills like me. :)

New changeset 5dd835edde1e by Georg Brandl in branch '2.7':
Closes #22868: make example less ambiguous.

Done. Thanks for the report!
